BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 727,489, dated May 5,1903.

Application filed December 29, 1902. Serial No. 137,081. (No model.)

To (LZZ whom it may concern:

Be it known that we, ARTHUR L. SYMMONDS and MARLIN T. SYMMoNDs, residingin the city of Colorado Springs, county of El Paso, and State ofColorado, have invented certain Improvements in Brick-Machines, of whichthe following is a specification.

This improvement relates to pressed-brick machines in which the clay isreceived in a slightly-moist condition, placed in molds, and subjectedto a very heavy pressure. When the brick is properly molded and pressed,it is raised from the mold and pushed forward through the gate onto atable by means of a plunger. From there it is loaded on a truck orwheelbarrow and taken away for further treatment. Heretofore thesemachines have proved faulty, because they allowed a rough feather-edgeto remain on the brick after it had passed through the gate. When thebrick were loaded on a truck for removal, this edge would be detached byits coming in contact with other brick and the grit and waste allowed todrop on and get between other brick and damage their smooth surface.

The object of this improvement is to overcome that fault and remove thefeather-edge and roughness before the brick leave the machine.

This improvement consists of the parts hereinafter set forth anddescribed and may be attached to any dry-press brick-machine.

WVe attain the objects of our invention by means of the mechanismillustrated in the accompanying drawings, in which-- Figure 1 representsa front View of an ordinary dry-press brick-machine with our deviceattached. Fig. 2 shows arms used in attaching our device to suchmachine. Fig. 3 shows a front View of one of. the bars which support ourbrush or scraper. Fig. 4 shows a rear View of the same bar, and Fig. 5 aside view of the same bar. Fig. 6 represents the metallic brush orscraper.

Like parts are referred to in all the figures by the same letters ofreference.

Referring to the details of the drawings, the letters A A represent thesides of the frame of a brick-machine.

B B B B represent the table projecting in front of such machine.

0 0 represent the right and left arms, which when attached to the frameform a support from which the scraper D is suspended.

D represents the scraper-bar.

E E E E represent the brick as they are being pushed out onto the tableB B B B.

a Ct a or represent the metallic blades, each of which are attached tothe bar D by means of the hinges b b and b.

d represents a fiat steel spring, which is attached at one end to thebar D by screws or rivets, as shown, the other bearing on the blades ona a a and causing the blades a to press on the surface of the brick asthey pass under, yet allowing enough movement to allow for slightvariations in the thickness of the brick.

g 9 represent hinges on the bars F. (More particularly shown in Figs. 3and 5.) The bar F is thus hinged to permit its being swung upward whenthe key 0 is raised above the staple r, as shown in Fig. 5. This allowsthe scraper to be displaced for the purpose of cleaning the dies andtable. The arms 0 C are attached to the frame of the machine by means ofscrews or bolts passing through the open slots m in the ends of the arms0 C. To the other ends of the arms 0 O are attached bars by means of thebolts 72, passing through the slots at and n in the arms and 7c 7c inthe bars, to which the scraper and parts necessary thereto are attached.

The elongated slots n n and 7t 70 will permit of the adjustment of theheight of the scraper for different machines and different thicknessesof brick. The elongated slots is it will also allow the bar to be raisedor lowered and may have a scale on it, so that the changes may be morereadily made.

The method of operation of our improvement is briefly described asfollows: \Vhen the brick E E E E are pushed upward from the molds andthen forward on the table B B B B, they are pushed under the blades ataa, a of the scraper. As they pass under these blades the blades bearfirmly on theirv surface, and any imperfection or feather-edge isscraped or brushed off, and the bricks leave the table clean, smooth,and perfect. When it is desired to clean the dies or table, the keys 0 0are raised and the scraper swung for" Ido ward and upward out of the wayon the hinges g g. When it is found that the scraper is not bearingevenly, is too high or low, because of Wear or change in the size of thebrick, it may be adjusted by means of the bolts 1' t' in the slots 70 k,or if a greater adjustment is to be madethen by loosening the bolt. hand permitting the bars F F to be shifted.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a pressed-brick machine the combinationwith the gate and table, of a metallic spring scraper or brush attachedthereto by means of arms and hinged bars, having slots
